"Uramichi Oniisan" is based on the same-name manga by Gaku Kuze that is serialized on the online manga magazine "comic POOL" that has over 1.5 million copies (inclusive of e-book) in circulation.
The main protagonist is the two faces 31 years old guy, Uramichi Omota (known as Uramichi Onii-san), who is working as a gymnastics coach on the educational program "Together with Mama". He is normally kind, but there are times where he will show a glimpse of his "dark side" and this work is a tragic eulogy for the "good child" that has become an adult.
The key visual has depicted the 5 main characters of "Uramichi Oniisan", which are Omota Uramichi aka "Uramichi Oniisan (Brother Uramichi)" (voiced by Kamiya Hiroshi), Usahara Tobikichi aka "Usao-kun" (voiced by Sugita Tomokazu), Kumatani Mitsuo aka "Kumao-kun" (voiced by Nakamura Yuuichi), Daga Iketeru aka "Iketeru Oniisan (Brother Iketeru)" (voiced by Miyano Mamoru", and Tadano Utano aka "Utano Oneesan (Sister Utano)" (voiced by Mizuki Nana).
